Thank you all for your input regarding your experience of sound changes after silver plating your instrument, but I was not interested to hear your experience, as I have my own allready.
I was & I am still very interested about the rationale behind the sound change as explained, so to know more about the physical process, which changes the sound appearantly. What happen with the instrument when plating ? I know already, that 5 Amp. per 16 square inches (SI) electricity is used for silver plating & 2 Amp for gold plating. The technician told me, that the result a bi-metal could cause the effect ??? Harder metal (brass) plus the softer metal surface (silver & gold) ??? Off course, the instrument is cleaned before the process: polished & ultra sonic degreased. But it was clean before, as I keep my instruments clean. The sound changes did occur with my 23 years old double as well with the brand new Viennese single. Well, brand new means, it has been used just for very few performances to be tested, the surface still shiny. So to make all clear. The old double was maintained perfectly, regularly cleaned inside & outside, not dents, no plaques. Just lacquer stripped. It was also a perfect horn when lacquere, but I got into difficulties when moved from the usual place in the pit to the brass side, sitting in front of the timps & playing verse the "sack" below stage or against the timps. Scientists, you are asked for an explanation. Thanks in advance.
